Which is a connecting link?a)Pilab)Peripatusc)Periplanetad)LimulusCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Correct Answer :- B

Explanation : Peripatus is a connecting link between annelids and arthropods. Its arthropods characters are claws, jaws, trachea and dorsal tubular heart. Its annelidan characters are continuous muscle layers in the body wall, unjointed legs and nephridia.

Answer

I think the answer should be D as it is connecting link between arthropods and Annelids . Its arthropods characters are claws, jaws, haemocoel, tracheae and dorsal tubular heart. The annelidan characters are continuous muscle layers in the body wall, unjoined legs and nephridia.

Answer

PERIPATUS is a connecting link between ANNELIDA and ARTHROPODA... LIMULUS is a living fossil also known as KING CRAB...so option D is correct..

Answer

Peripatus is the connecting link betwèen anelida and arthropoda .
limulus is a living fossil

Answer

answer should be D as it is a connecting link between arthropods and annelids option B is a living fossil

Answer

limulus also called king crab is a living fossil peripatus is the connecting link between anelida and arthropoda so op d is most appropriate

Answer

Option D..... #Peripatus is the connecting link between annelids and arthropods......💯💯💯

Answer

answer is d

Answer

Connecting Link in Evolution:
A connecting link in evolution refers to an organism that exhibits characteristics of both primitive and advanced organisms, thus serving as a link between two major groups or species. These organisms provide evidence for the evolutionary transition between two groups and help scientists understand the evolutionary relationships among different organisms.

Explanation of the Answer:
Among the given options, Peripatus (option B) is considered a connecting link. Peripatus, also known as velvet worms, belong to the phylum Onychophora. These organisms exhibit characteristics that are intermediate between annelids (segmented worms) and arthropods (insects, spiders, etc.). They are found in tropical and subtropical regions, inhabiting moist environments like leaf litter, soil, and rotting logs.

Characteristics of Peripatus:
Peripatus possesses several characteristics that make it a connecting link:

1. Segmented Body: Peripatus has a segmented body similar to annelids, with each segment having its own pair of legs. This is a characteristic shared with primitive organisms like worms.

2. Tracheal System: Like insects and other arthropods, Peripatus possesses a tracheal respiratory system. This system consists of a network of tubes that deliver oxygen directly to the tissues.

3. Claw-like Appendages: Peripatus has claw-like appendages called onychophoran claws, which are used for grasping prey. These claws are similar to those found in primitive arthropods.

4. Primitive Reproductive System: The reproductive system of Peripatus is considered primitive, as it has separate sexes with internal fertilization. This is similar to the reproductive systems of annelids and some primitive arthropods.

5. Simple Excretory System: Peripatus possesses simple excretory structures called nephridia, which are similar to those found in annelids.

Conclusion:
Therefore, Peripatus (option B) is considered a connecting link in evolution due to its combination of characteristics from both annelids and arthropods. It provides valuable insights into the evolutionary history and relationships among these groups of organisms.
